Watching a movie called Europa Report. Really good so far. My only problem is... okay, so on this space walk to repair something, one of the men's tether snaps and he goes floating off into space. There's only 20 minutes of oxygen, and the other guy had a hole in his suit and couldn't rescue him. But the thing is, don't astronaut suits have thruster packs on their back to move them forward back to the ship in case the tether breaks? Because that's a huge oversight on the writers' part if so.
